Interstitial Condensation In Roofs
Interstitial condensation is when the condensation is formed in the core of the structure while surface condensation is formed on the inside surface of the wall or roof.
Interstitial condensation in roofs. Inside the roof wall or floor elements. Interstitial condensation can cause deterioration or even failure of the components of the assembly potentially shortening their useful lifespan. Interstitial condensation is condensation which occurs between layers of the construction i e. Interstitial condensation is condensation which occurs between layers of the construction i e.
Interstitial condensation commonly occurs when moist air permeates through elements of the building fabric across which there is a temperature difference typically but not always when warm moist internal air moves towards the cooler outer parts of external walls or roofs driven by a pressure difference. Interstitial condensation can cause deterioration or even failure of the components of the assembly potentially shortening their useful lifespan. Sometimes it can occur within the structure of a wall if it is made of very porous material. Interstitial condensation is a type of condensation which takes place between layers of a structure.
Interstitial condensation is a form of structural damp that occurs when warm moist air penetrates inside a wall roof or floor structure. Interstitial condensation refers to condensation occurring within spaces or interstices and usually this means within stud walls or the rafter spaces of a house with a room in the roof with rafter level insulation. When that moisture laden air reaches a layer inside the interstitial structure that is at dew point temperature it condenses into liquid water on that surface. Condensation risk analysis cra.
Inside the roof wall or floor elements. Interstitial condensation can create structural dampening that occurs when moist air penetrates inside the hidden space within an enclosed wall roof or floor cavity structure. Therefore it is of paramount importance to ensure that any roofing materials used are designed in a way of which prevents interstitial condensation by creating adequate amounts of ventilation that removes any condensation build up.
